I have an RCA D56W20 and the color on the screen start getting red then it turned green then it shut off . Now when you turn it on it all green and can barely see the picture. What is wrong is it my lamp or some kind of color switch? Also how much will it cost to fix. The TV is 6 years old not sure if worth fixing.

try contacting the manufacturer or the better business bureau

The green CRT has an issue and will need to be replaced. It could be the Green CRT drive board but doubtful as your describing the classic sign of a CRT thats developing a Short . You can get replacement green CRTs and CRT drive boards from www.tvrepairworld.com

Those type of tv sets get unusually hot at times. Could be a heat issue. Power flow at night is the best. If it's still turning off then, it must be a dust or heat issue.

Projection TV sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the video to look normal. When its out of alignment the video will look 3D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the TV menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired.

This is a very common failure on these projection sets and a fairly simple DIY fix. All projeciton sets including Samsung, RCA, Sony, Philip Magnavox, Panasonic, Pioneer, Akai, GE, JVC, Toshiba, and others at some point will have the same problem.

Common Symptoms include....

• Screen looks 3D
• Colors don't line up
• One or more colors can't be adjusted when using the convergence menu.
• Screen is bowed or warped.
• TV shuts off after powering on. Power light will blink. TV may also make a chirping noise.

Here are some photos of convergence problems.






Here is a quick test....

Using your original remote go-to the settings menu then goto the convergence section.

Try to adjust the red and then the blue convergence.

You should be able to move RED and BLUE in all directions - up, down, left, and right. And you should be able to get the grid straight.

If you can't move them in all directions or cant move them far enough your convergence chips are bad and should be replaced. This is a common problem.

Note: If you TV has as flash focus or magic focus button only try pressing the button. If it fails to fix the convergence your need to fix it. See below for a fix

CONVERGENCE SOLUTION

You will need to replace the convergence chips and possibly some convergence resistors and pico fuses.
This is a a fairly easy DIY job if you are handy and can follow directions. You can get complete repair kits from TvRepairKits.com or click here. They have put together DIY repair kits that include the OEM parts and step by step photo instructions for each repair. If you are not handy or can't follow directions we would suggest calling a shop.

The projection TV has 3 guns RED GREEN BLUE. In your case the red and the blue guns are gone. So you are getting the green color screen. You got to replace the picture tube.

Sounds like the color wheel stopped and re-started. It may continue to function for a while, but could fail at any time.

I've also seen on rare occasion, a defect in a lamp produce uneven color rendition, but its far more likely that the culprit is the color wheel.

id be calling the friend asking for a refund...what you have going on is pretty common but did you see it work prior to buying it or just take their word for it? you may have a bad flyback or transformer but it shouldnt be bad so soon after you happened to buy the tv and no it would not have gone bad from moving the tv

your convergence powert supply is not working-
replace the supply or repair it

move your streo speakers or any thing w/magnet

CHECK VALUE OF RESISTORS IN CRT BOARD,,,,AND THE 3 TRANSISTORS COLOR DRIVERS ....THATS AUTO SHUT DOWN FOR OVER VOLTAGE....DO YOU SEE RETRACE LINES BEFORE SHUTDOWN?IF YES TRY TO LOWER DOWN SCREEN FIRST ON THE FLYBACK TO SEE IF ITS GOING TO SHUTDOWN.....
